VETERINARY SURGICAL TABLE.

Application filed March 25, 1919.

T 0 all to 7mm it may concern Be it known that we, TI-IoMAs OLrNenR andFRANK STALKER, citizens of the United States of America, residing atHolland, in the county of Ottawa and State of Michigan, have inventedcertain new and useful Improvements in Veterinary Surgical Ta bles; andwe do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to veterinary surgical operating tables,particularly tables adapted for use in caring for small animals,

the present invention being an improvement over that shown in a formerapplication, Ser. No. 210,976, filed Jan. 9, 1918, for surgicaloperating table, by Thomas Clinger. It is an object and purpose of theinvention to provide a table consisting of two parts which may beindependently adjusted with relation to each other and the support whichcarries the table, and thereafter held rigidly in any position ofadjustment, a particularly strong and rigid construction being made. Afurther object is to provide a particularly novel means of adjustmentfor the parts of the table, and one which can be very readily and easilyoperated, while the manufacturing cost is greatly reduced over theconstruc tion shown in the application above noted. These featurestogether with many others will appear fully and in detail as thedescription progresses, reference beinghad to the accompanying drawingsshowing a preferred and practical embodiment of the invention, in whichdrawings,

Figure l is a side elevation of the table,

Fig. 2 is an end view of the table and upper portion of the supporttherefor.

Fig. 3 is a fragmentary vertical section through the support and showingthe means of angular adjustment of the table as a whole, and

Fig. 4 is a fragmentary enlarged side elevation, partly in section,illustrating the adjustable connection of the table parts to itsimmediate supporting means.

Like reference characters refer to like parts in the'different views ofthe drawings.

The table as a whole is carried and supported at the upper end of ahollow column 1 which is equipped with a plurality of Specification ofLetters Patent.

diverging legs 2 at its lower end, the same having casters or the liketo permit ready movement of the column over the floor. The upper end ofthe column is divided, making two upstanding spaced apart arms 3 to theupper ends of which a bar 4 is pivotally mounted at its middle asindicated at 5. A sector 6 is cast integral with the bar t and passesbetween the arms 3 ofthe column, being provided with a plurality ofspaced apart notches 7'in its outer edges as shown.

In the upper end of the column a U- shaped member 8 is inserted, theupper ends of the legs thereof being connected by a cross bar, the ends9 of which extend beyond the sides of member 8 and rest on the coiumnbetween the lower ends of the arms 3. Adjusting screws 10 pass throughopposite sides of the column and thread into the opposite legs of themember 8, and it is evident that such member 8 may be adjusted todifferent positions with respect to the column and held in any positionto which adjusted.

2i rod 11 passes freely through the bottom of the member 8 and the upperconnecting cross bar,'its upper end. being designed to enter any of thenotches 7 At the lower end of this red a wire 12 is connected and acoiled spring 13 is seated on the bottom portion of the member 8 andunder com pression acts to elevate rod 11 and force it into the notches.iVhen a change in position of the sector 6 is desired, the rod 11 may bemoved downwardly by operating a foot lever 14 to which the lower end ofthe wire 18 is connected, said lever being pivotally mounted at one endon one of the legs 2. The adjustment of the member 8 described is forthe purpose of adjusting the upper end of the rod 11 to enter the centernotch "Z properly so that the table carried by the bar 4: shall beperfectly horizontal, it being evident that variations due to shrinkagein casting, or from other causes, in the position of the central notch 7may be readily compensated by this adjustment..

downwardly around the inner ends of bars 17 as indicated at 19, therebeing formed an open slot between the table parts which e2 tends theentire length of the table. This structure furnishes an open drainthrough which matter may pass to a drain trough 20 disposed lengthwiseof and below the slot and resting on the brackets 15 between the legs16. The trough is held against removal by a hook 21 which may detachablyconnect with a suitable eye on one of the legs 16 as shown in Fig. l,but on disconnection of the hook, the trough may be readily removed iorcleaning. Theouter edges of the table parts 1.8 are bent and formed asindicated at 18 making vertical outer surfaces to which hooks or thelike of conventional form may be attached for the purpose of connectingwith securing ropes or the like used to hold the animal on the table.Hooks 22 are connected at each end of the drain trough for supporting apail or like device into which the drain trough may empty.

Two levers 23 are'placed with their inner portions side by side at eachend of the bar 42, each of said levers being formed at 1ts inner endwith a notched sector 24, the notches being spaced apart a shown. Thelevers at each end of bar 4 extend outwardly in opposite directions andeach is pivotally connected to the end of the bar 4 by a stud 25 passingthrough a slot 26 in the lever.

' The studs 25 are o1 a size to readily enter any notch in a sector 24:,and the stud on which one lever 23 is pivotally mounted serves as a stoppin or stud for the other lever, entering a notch in its sector end 24.By reason of slots 26 in the levers 23, the levers may be pulledoutwardly to disengage from studs 25 with which their ends 24: engage,and the levers then turned to another position for the studs to enterother notches in said ends 24:. The studs 25are threaded, one at eachend receiving a locking hand wheel 27 and the other a nut 27 the handwheel being operated. to look at least one of the levers 23 associatedwitha table part 18 against movement.

Each of the bars 17 is formed with a downwardly extending lug 28 at apoint between its ends. A rod 29 is pivotally connected at its upper endto each of the lugs 28 and at its lower end has threaded connection witha member 30 connected to a lever 23, each of the levers being connectedin this manner with a bar 17. The levers are formed with hand holds attheir outer ends so that it is easy and convenient to grasp the'ends ofthe pair of levers at either side orthe table, draw out on the same todisengagethe ends 24: from the studs 25, tilt the table part 18 to anydesired position, and push in on the levers to engage again with thestuds, after which the locking hand wheel. may be tightened to rigidlyhold the part 18 in position and insure against possibility ofdisengagement. Either side 18 may be tilted independently of the otherand to any preferred position or angle. And the table as a whole maylikewise be turned about the pivot 5 to different angles to the 1. Anoperating table comprising two table members located with adjacent sidedges spaced a short distance apart, a .bar located lengthwise of andunder the table members at the inner edges thereof, a bracket connectedto each end of the bar, each of said brackets having two upwardlyextending spaced apart legs, the table members having pivotal connectionthereto, and means mounted on the ends of the bar and connected witlrthetable members 'for moving either of said members to different positionsabout their pivotal connection to the legs of said brackets, and forholding said members in any positions to which they may be moved.

2. An operating table comprisin a support including a bar, a bracketattached to each end 01": the bar above the same, each bracket havingtwo upwardly extending spaced apart legs, two table members of sheetmetal located with adjacent edges spaced a short distance apart, barslocated transversely under each table member and secured thereto, theinner ends of the bars having pivotal connection to the upper ends ofthe legs of the-brackets, two spaced apart studs extending from the endsof the first bar, two operating levers at each end of the first bar,said levers having inner ends placed side by side and each having a slottherethrough through which a stud passes, the inner ends of the leversbeing formed with notched sectors adapted to engage with the studs, andmeans connecting each lever with one of the bars under a table member,substantially as and for the purposes described. r

3. An operatingtable comprisinga main 7 supporting bar, two tablemembers located side by side with adjacent edges spaced a short distanceapart, means for pivotally connecting each of the table members adjacentits inner edge to each end of the bar,

two levers located at each end of the bar and extending in oppositedirections, the inner ends of said levers overlapping and having pivotaland slidable connection to the bar, means connecting the leversextending to either side of the bar with the table member above thesame, and interconnecting means between the lovers and the ends of thebar for holding said levers in any of a plurality of positions to whichthey may be moved with respect to the bar, substantially as described.

4. An operating table comprising a main supporting bar, a studprojecting from each end of the bar and to one side thereof, a leverlocated against each end of the bar and having a slot therein throughwhich the stud passes, said lever being formed with a sector having aplurality of spaced apart notches therein, a second stud extending fromeach end of the bar at the opposite side thereof and adapted to enterany one of the notches in the lever, said lever being longitudinallymovable to disengage from r the stud, a second lever pivotally andslidably mounted on each of the second studs, said; second levers lyingagainst the first levers and having similar notched sectors at theirends in which notches the first studs are adapted to enter, two tablemembers located above the bar and adapted to lie in the same plane withadjacent edges spaced a short distance apart, means for independentlypivotally connecting each table member to the bar, and a rod connectingeach of the levers to a table member, two of the levers being connectedto each table member, substantially as described.

5. An operating table comprising a 1101- low supporting column, saidcolumn having two upwardly extending spaced apart arms at its upper end,a bar located at the upper ends of said arms and pivotally connectedthereto, said bar having a sector formed With a plurality of spacedapart notches passing between the arms, a U-shaped member located in theupper end of the column at the lower ends of the arms, adjusting screwspassing through opposite sides of the column and threading into oppositelegs of the U-shaped member, a foot lever pivotally connected at one endat the lower end of the column, a rod passing through the bottom of theU-shaped member and extending upwardly to the sector, being adapted toenter any of the notches in the sector, a spring seated on the U-shapedmember tending normally to elevate the rod, a wire connecting the lowerend of the rod and the foot lever, and a table carried by the bar.
